Zusammenfassung:A head module 10m includes a head 11, a pair of driver ICs 12, a holder 13 that supports the head 11, a head spreader 14 in thermal communication with the pair of the driver ICs 12 and a heat insulator 15 located between the heat spreader 14 and the holder 15. The heat insulator 15 has a thermal conductivity lower than the heat spreader 14.
